Like the large envelopes. Yet, I'm not sure why the clasp envelopes are cheaper to purchase than non clasp. Postal service recommends covering the clasp area with a piece of tape to make it easier for the sorting machine, but this step of taping the area could be eliminated if the cost was less for the none clasp.

We order this product a lot. We have noticed the last couple times we have ordered them that they have not been sealing as well as they used to and the bottoms have not been sealed on all of them so we have to tape them shut. The clasps have also not been fastened to the envelope very well and have been falling off easily. It just seems like they are not put together as well as they used to be.

Our company was very impressed with the quality and endurance of these envelopes. The size is a big plus for storing a lrge ammount of documents in and also mailing catalogs, folders or many documents at once.
